Any person of mexican decent in the USA who is currently eating up our resources, and adding a horrible smell to most of the south, also ruining the economy.
Can be spotted usually covered in garbage and reaking of tacos. In essence those persons who are killing America, wont stop speaking in pig latin and are also generally worthless.

Mexican Americans...
Lack an education,
so they go to night school, and take Spanish and get a B...
Mexican Americans...
Don't just like to get into gangfights,
they like flowers and music and Whitegirls named debby too..

An oxymoron used to describe an American who is from or ancestors were from Mexico. Mexican is a nationality and colonial identity, but not an ethnicity. One cannot be a citizen of Mexico and a citizen of the United States at the same time. One can be from one of the ethnic groups indigenous to Mexico and be a citizen of the United States.

One can be Mayan-American, Nahuatl-American, Zapotec-American, etc., but not Mexican-American.

Many so called Mexican-Americans are descendants of the Spanish colonial population. They cannot be called Spanish-American as Spanish is not a distinct ethnicity but a national and colonial identity as well. They fall under the category of "White".
